Jinn (Arabic: Ø§ÙØ¬Ùââ, al-jinn), also romanized as djinn or anglicized as genies (with the more broad meaning of spirits), are supernatural creatures in early Arabian and later Islamic mythology and theology. An individual member of the jinn is known as a jinni, djinni, or genie (Ø§ÙØ¬ÙÙ, al-jinnÄ«). They are mentioned frequently in the Quran (the 72nd sura is titled SÅ«rat al-Jinn) and other Islamic texts.
Once you tighten up and lose range of motion in your arms, it reduces stride length, which is difficult to get back without burning a lot of energy. While sprinting, it is important to get a full range of motion with the arms. Remember, speed is a product of stride length and stride frequency. Stride length and frequency are determined, in part, by the motion of the arms. If you are lazy or passive with your arm action, you are limiting your potential for speed.
Arm span or reach (sometimes referred to as wingspan) is the physical measurement of the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a one-hundred eighty degree angle. The average reach correlates to the person's height.n above-average reach is advantageous in sports such as basketball, boxing, discus throw, fencing, and swimming. For instance, boxer Sonny Liston had an 84-inch (213 cm) reach despite being only 72 1â2 inches (184 cm) in height.
